Story
Meet Rex, our 98-lb gentle giant with a heart just as big as his blocky head. This stunning red Mastiff mix, just under 2 years old and already neutered, is the total package he is calm, polite, intelligent, and just the right amount of goofy. ✨ Why Rex is amazing: • Walks beautifully on leash • Knows “sit” and takes treats with a soft, gentle mouth • Affectionate once he warms up • Loves walks, lounging, and hanging with his people • May be cat workable with slow and proper intros 🐱❤️ In playgroups, Rex enjoys gentle play with both male and female dogs who don’t mind his big-dog enthusiasm. He thrives in a calm, structured home without too much chaos just a loving person or family who sees what a treasure he is. Neutered| 2 yrs old | 98 lbs | Mastiff Mix

Good with kids, Not good with cats, House-trained, Shots are up-to-date,
Story
Meet our sweet boy Apollo 🐾 Apollo just turned 2 years old on January 5, 2026. He is a loving, affectionate pup who adores belly rubs and enjoys spending time with his people. Apollo is well-mannered and knows basic commands such as sit, stay, lay down, and shake paws. We are heartbroken to say that we are looking for a new family for Apollo due to circumstances beyond our control—our landlord has required that we rehome him. This decision has not been easy, and our only wish is to find a home that will love and care for him just as much as we do. If you are willing to give Apollo a chance and provide him with a safe, loving forever home, please reach out. He truly deserves a family who will cherish him.
